Emulate non-number numpad keys?
As mentioned the \ is already set for local view, the = (+ without shift) and - are also set to replace the numpad +/- (for zoom in/out). For others you most likely want to setup some custom keys.

In the Input preferences you can search for key-bindings containing numpad and then adjust the ones you want to use by clicking the key display and choosing another key. The issue is finding a key that isn't used or that you don't make use of, then save your settings so they are always available.



You may find that the [ or ] can be used as they are shortcuts to brush size when sculpting/painting where F is more well known. Also 2,4,6,8 and 9 are less used by many people.
